Installation Procedure

INSTALL OR CONNECT
^ Tools Required:
- J 3289-20 Holding Fixture Base
- J 3289-21 Holding Fixture
- J 37769 Differential Holding Fixture Adapters
- J 8614-01 Flange Holder
- J 24433 Side Bearing Installer
- J 8107-4 Differential Side Bearing Remover Plug
- J 8092 Driver Handle
- J 37758 Pinion Outer Race Installer
- J 37759 Pinion Inner Bearing Race Installer
- J 8001 Dial Indicator Set





1. Differential pinion gears, washers and side gears with selective washer into differential case.
2. Pinion shaft into differential case.

Measure





- Left differential side gear end play using J 8001. Place the plunger between the teeth of the left side gear and move the left side gear up and down using two screw drivers while observing J 8001. Left side gear end play should measure 12 to 37 mm (0.005 to 0.014 inch). If left side gear end play is too high or low, replace the side gear selective washer with the appropriate size to obtain correct end play.
- Right differential side gear end play using J 8001. Place the plunger on the rear of the right differential side gear and using the finger tips of both hands, gently move the right differential side gear up and down while observing J 8001. Side gear end play should measure 12 to 37 mm (0.005 to 0.014 inch). If side gear end play is too high or low, replace the side gear selective washer with the appropriate size to obtain correct end play.





3. Pinion shaft roll pin into differential case and through pinion shaft. Roll pin end should be even with the differential case surface.





4. Ring gear to differential case; secure with ten bolts.
- Tighten ring gear bolts to 85 Nm (63 ft. lbs.).

Important: After correct end play has been obtained, remove the ring gear bolts and apply GM P/N 12345493, or equivalent, to the threaded portion of each ring gear bolt and install into differential case.





5. Side bearing on the left side of the differential case assembly using J 37758 with J 8092. Place the differential case assembly on a hydraulic press and using J 37758 with J 8092, place the left differential side bearing on the left differential case with the tapered side up and slowly press the left differential side bearing onto the left differential case.





6. Side bearing on the right side of the differential case assembly using J 24433 with J 8092 and J 8107-4. Place the differential case assembly on a hydraulic press using J 8107-4 for support and to protect the left differential side bearing. Then, using J 24433 with J 8092, place the right differential side bearing on the right differential case with the tapered side up and slowly press the right differential side bearing onto the right differential case.





7. Inner pinion bearing race into the differential carrier using J 37759 with J 8092. Place the differential carrier on a hydraulic press and position the inner pinion bearing race over its bore. Then, using J 37759 with J 8092, slowly press the inner pinion bearing race evenly into the differential carrier.
8. Outer pinion bearing race into the differential carrier using J 37758 with J 8092. Place the differential carrier on a hydraulic press and position the outer pinion bearing race over its bore. Then, using J 37758 with J 8092, slowly press the outer pinion bearing race evenly into the differential carrier.
